Subject: MTRR driver model support broken on SMP.
Date: Wed, 04 Aug 2004 12:07:21 +1000 [thread overview]
Message-ID: <1091585241.3303.6.camel@laptop.cunninghams> (raw)
Hi all.
MTRR driver support is broken on SMP because it calls smp functions with
interrupts disabled, but interrupts should be disabled because it is
called via device_power_up.
Badness in smp_call_function at arch/i386/kernel/smp.c:565
